Impetigo contagiosa staphylogenes is commonly treated by administering a combination of nadifloxacin and tetracycline ointments. However, it is not clear whether nadifloxacin and tetracycline are stable after mixing. The purpose of this study was to evaluate the stability of these agents in combination. We also evaluated changes in antibacterial activity after mixing. Mixing the two ointments caused tetracycline to change from yellow to brown in the admixture. Furthermore, the tetracycline content in the ointment decreased in a time-dependent manner, to about 40% at 288 h after mixing. In addition, the nadifloxacin content in the ointment did not change 288 h after mixing. In an alkaline environment (pH 9.0 and 11.0), the tetracycline content decreased and the color of tetracycline changed to brown. These results suggest that sodium hydroxide, which is an additive in nadifloxacin ointment, influences the content of tetracycline. We evaluated the chemical sensitivity of Staphylococcus aureus using disk tests. Nadifloxacin and tetracycline ointment showed the largest radius of inhibition circle, followed by the admixture 0 h after mixing and the admixture 72 h after mixing. These results suggest that the antibacterial activity is inhibited by the admixture. We propose that pharmacists should avoid mixing nadifloxacin with tetracycline ointment in the treatment of impetigo contagiosa staphylogenes and should take care to avoid interactions caused by additives in the ointments.

The proclamation of April 2002 of a Ministry of Health, Labor and Welfare ordinance has enabled doctors to prescribe drugs for an outpatient without a limit on the length of prescription terms except for a few drugs. There is a concern that the prescription-term deregulation could cause careless drug therapy management in order to extend the interval between patient hospital visits. The purpose of this study is to make pre- and post-deregulation comparisons of two items, prescription terms and implementation of clinical examination that complied with package-insert precautions, and to discuss the approaches to increase safety. Prescription terms have lengthened progressively. In the preregulation period of January to March 2002, the mean prescription term was 19.9 days; in the post-regulation period of July to September 2002, it was 24.9 days; and in July to September 2003, 28.6 days. Even for anti-tumor agents, there were prescriptions over 90 days after deregulation. There was no significant difference between the pre- and post-deregulation compliance ratios for the package-insert precautions in eight drugs of investigated nine. However, one case had a delay in detection of liver dysfunction, which was caused by deviation from the once-a-month testing indicated in the package-insert precautions for prolonged prescription terms. The evidence suggested that the deregulation led to negligent drug therapy management. To assure safe therapy, the following should be addressed : first, sufficient function of a computerized prescriber order entry system and second, creation of a new framework with pharmacists' active involvement such as collaborative therapy management with physicians.

To deal with missing data in clinical tests, three methods (A, B, and E) were considered. Drug efficacy was estimated by (A) using only actual data, (B) using a previous value for a missing datum, and (E) using the value estimated by the equation (1) for a missing datum. [numerical formula] where S is the symptomatic severity (S0 is at the beginning), b is the recovery rate constant, θ is the number of days after the initiation of medical treatment, and subscript i means the i-th judgment. Based on theoretical calculations and analyses of nine sets of real data in ophthalmology, orthopedics and dermatology, (i) drug efficacy estimated by B was always smaller than by E, (ii) the difference in estimated drug efficacy between A and E was very small.
